调试 WordPress 电子邮件功能



我正在接管一个wordpress网站,我已经从wordpress转移到了Azure。该网站底部有一个按钮,单击时会发送电子邮件。这是 onclick 方法的 html

<div class="w-form-json hidden" onclick="return {ajaxurl:http://loancoreignite.azurewebsites.net/engine/wp-admin/admin-ajax.php,success:Thank you! Your message was sent.,errors:{name:Please enter your Name,email:Please enter your Email,phone:Please enter your Phone Number}}"></div>

当我转到该 ajax url 时,我在左上角得到一个 0,调试工具中出现 404 错误。所以我找到了 admin-ajax.php 文件并尝试从那里弄清楚它,但这就是我迷路的地方。下面是 admin-ajax.php 文件。

    <?php

也许这比我想象的更容易,所需要的只是wordpress中的东西?

你可能不是,但我觉得有义务说出来:

请不要编辑WP核心文件!!

至于你的问题,可能是很多事情。WP Ajax需要设置一个"动作"。有关设置 AJAX"操作"的更多信息,请参阅此链接:https://codex.wordpress.org/Plugin_API/Action_Reference/wp_ajax_(操作(

其次,当WP AJAX返回0这意味着找不到AJAX"操作"(如上所述(,或者PHP函数最后没有die()您必须在 AJAX 触发的 PHP 函数末尾添加die();,并且必须从上面的链接声明操作。

创建一个 PHP 函数以在您的函数.php文件中发送电子邮件。从上面的链接创建操作,并将回调设置为 PHP 函数。在函数结束时,放入die();然后事情应该开始按预期工作。

有两种类型的 AJAX 操作,wp_ajax-your-functionwp_ajax_nopriv-your-function 。两者中的第一个将允许从 wp-admin 完成您的 AJAX 请求,第二个(带有 _nopriv 的那个(将允许您从前端触发您的 ajax 请求。

如果你需要一个例子,就问。我可以从现有站点中提取一个来向您展示。

需要修复你的JSON

<div class="w-form-json hidden" onclick="return {ajaxurl:'http://loancoreignite.azurewebsites.net/engine/wp-admin/admin-ajax.php',success:'Thank you! Your message was sent.',errors:{name:'Please enter your Name',email:'Please enter your Email',phone:'Please enter your Phone Number'}}"></div>

即使我仍然看不出这是怎么做的。
